Reference Priors Versus Reverse Reference Priors: The Role of Invariance [PDF]
The Egyptian Statistical Journal, 2000 In this article, I investigate two classes of noninformative priors: the reference priors of Berger and Bernardo and the reverse reference priors attributed to J.K. Ghosh.

Weight Reparametrization for Budget-Aware Network Pruning
, 2021 International audiencePruning seeks to design lightweight architectures by removing redundant weights in overparameterized networks. Most of the existing techniques first remove structured subnetworks (filters, channels,...) and then fine-tune the ...

Dynamics of a family of rational operators of arbitrary degree
Mathematical Modelling and Analysis, 2021 In this paper we analyse the dynamics of a family of rational operators coming from a fourth-order family of root-finding algorithms. We first show that it may be convenient to redefine the parameters to prevent redundancies and unboundedness of ...

Traction Force Microscopy for Viscoelastic Substrates: A Semi‐Analytical Method
Advanced Science, EarlyView.A semi‐analytical viscoelastic traction force microscopy framework is introduced for quantifying time‐resolved cell tractions on flat finite‐thickness substrates. The method generalizes elastic traction force microscopy to Generalized Maxwell materials, identifies when elastic approximations remain valid and, when they do not, shows that inferred ...

Hydrodynamics of Two-Dimensional CFTs
UniverseWe demonstrate that the geometric action on a coadjoint orbit of the Virasoro group appropriately describes non-dissipative two-dimensional conformal fluids.

The effective action of superrotation modes
Journal of High Energy Physics, 2021 Starting from an analysis of four-dimensional asymptotically flat gravity in first order formulation, we show that superrotation reparametrization modes are governed by an Alekseev-Shatashvili action on the celestial sphere.

Field reparametrization in SMEFT [PDF]
The European Physical Journal Plus, 2017 Debate topic for effective field theory (EFT) is the choice of a “basis” for ${\rm dim}= 6$ operators. Clearly all bases are equivalent as long as they are a “basis”, containing a minimal set of operators ...

AI‐Physics‐Experiment Trinity for Integrated Protein Dynamics Modeling
Advanced Science, EarlyView.This review unites experiments, physics‐based simulations, and AI as a synergistic triad for protein dynamics modeling. It highlights integrative strategies, resolves sampling and forcefield bottlenecks, and outlines challenges and future directions for accurate, interpretable conformational ensemble prediction.

The Geometry of Neural Nets' Parameter Spaces Under Reparametrization
, 2023 Model reparametrization, which follows the change-of-variable rule of calculus, is a popular way to improve the training of neural nets. But it can also be problematic since it can induce inconsistencies in, e.g., Hessian-based flatness measures ...

Model‐Enabled Knowledge Transfer Across Cell Lines, Culture Scales and Conditions
Biotechnology and Bioengineering, EarlyView.ABSTRACT Mechanistic models are central to quantitative understanding and optimization of Chinese hamster ovary (CHO) cell culture processes, but their utility is often restricted by parameter sets calibrated for specific cell lines, scales, or operating conditions.
